Building Meta's GenAI Infrastructure
Meta's infrastructure team walks through the two versions of their 24,576-GPU training cluster built to train Llama and support GenAI research at a scale most of us will never operate at directly, but the design tradeoffs around networking, storage, and power show up at a tenth the size too. What I appreciated most is the honesty that GenAI workloads broke assumptions their existing infrastructure had baked in for years, forcing real architectural changes rather than just adding more machines. Good grounding for understanding what "AI infrastructure" actually means below the model layer.
